server: new statement details endpoint

New endpoint for Statement Details. The endpoint returns:
- Statement: the total stats for that statement fingerprint
- StatementsPerAggregatesTs: returns the statement from the period
selected but each aggregated timestamp is an entry. This list
can be used on the overview page on the Statement Details for
the creation of charts by aggregation timestamp.
- StatementsPerPlanHash: returns the statement from the period
selected but each plan hash is an entry. This list can be used
on the Explain Plan tab of the Statement Details, to show the
execution stats per Plan.

Partially addresses #72129

Release note (api change): New Statement Details endpoint that returns
the details for a selected statement, and its execution separated by
aggregation timestamp (statementsPerAggregatedTs) and by plan hash
(statementsPerPlanHash).
